When working with the node.js repl, is there a way to quit a continuation line that node is being over zealous with?

For example:

$ node
> {- -}
...

And pretty much everything you can type then gives you another continuation line. Ctrl+D quits the whole repl.

Obviously I don't want to go around typing {- -} all the time, but I do find I often type something erroneous when I'm using the repl to experiment. Then I have to quit the repl, and loose all the bits in memory.
